Beware of online trolls. It's best to avoid reading the 'comments' section of any news site. You have more important things to do than argue with bigots. Even posting a witty retort to a nasty person will drag you down. You may think airing opinions won't affect your reputation, but it will. The last thing you want is to lose business because someone takes offense at a casual comment. It's also wise to wait a full day before responding to upsetting emails and text messages.
